I thought if you had a campsite the cars in the overflow lot were free. If you had a cabin they charged you. I think parking of multiple cars on the campsite is frowned upon, but not enforced.OK, cool. I'm not as worried about the size of the pad . I'm pretty confident that I can fit a few cars on it. I more concerned about how the parking is charged for a 2nd or 3rd car, that i can fit on the concrete pad.
